2301-:L175 _\CK(ll~OUND 0l~ 'Ill[. INVENrION
FIELD OF TllE [NVENTIO_ Tllis invention relates to the art of soap making, and more particularly to a process Eor el:imination of objectionable cracking in soap.
DESCRII'TION OF TtlE PRIOR ART
New test methods for evaluating soap bar and cake wet cracking problems are d:isclosed in United States Patent No .
4,147,053. Based on the application of these new tests and the observations of the results, it has been discoverecl that toilet soap bars made by the single extrusion process showed a somewhat laminar or parallel crack pattern in the cross sectional test.
These bars, in general, did not develop severe wet surface cracks when subjected to the wash room usage test. Contrastingly, bars made by the dual extrusion process have a generally non-parallel crack pattern with radical spurs radiating always preferentially to one side and across the short axis of the bars. These bars, when field tested, would consistently develop severe wet surface cracks always significantly more on one side than the other. The ~0 problem existing in the prior art dual extrusion wet surface crack-ing was to devise a means for imparting a laminar or parallel crack pattern to the finished bars.
Further, in the past, high moisture containing soap bars have been produced by plodding of the soap mass through a cone noz-zle with two extrusion ports so that two streams o-f plodder blanks can be fed into a duplo-press for sustaining higher line speed and efficiency.
I-lowever, changes in formula and bar shape generally re-sult in unusual and excessive surface cracks on the face of the U.S. No. 314,641 -2-I . R. 3827 '7~i5 ,~ I
¦¦ bars witi-~ one side more pronouncecl than the ottler. This problemI is directly relatecl to the dual extrusion soap ploddincJ proeess and the conventional method of pressing tlle soap blanks on the internal cut face and external face.
Il l I S~MMARY OF TIIE INVENTION
Il j Through a series of plodder blank shapes and pressing experiments, it has been discovered that by pressing square or semi-square plodder blanks, whieh were intentionally re-oriented or ro-tated by ninety degrees on -their longitudinal axis, the bar ¦
surfaee cracks disappeared.
Subsequently, these bars were subjeeted to the eross sectional wet cracking test according to Uni-ted States Patent No. 4,147,053. The results showed the desirable formation of Il a laminar or parallel cracking pattern. In wash room tests, ! toilet soap bars with this type of cracking pattern have eonsist-ently exhibited no tendeney to develop objectionable wet surface I eraeks.
i Aeeordingly, the present invention eomprises the steps of extruding plodder blanks and then rotating these blanks on their longitudinal axis to obtain the unexpeeted formation of ¦ a laminar pattern and eliminate both stress surfaee eraeks and wet surfaee eraeking when the soap is introdueed in its rotatecl state into -the soap press.

trusion of pairs of soap plodder blanks fOrevery formula of I soap now in pro~lucLioll while forminq in the finished soap bars a ¦ laminar or parallel pattern of a sound soap bar or cake thereby ¦ eliminating stress surface cracks and objectlonable wet cracking.

on the nozzle cone of a plodder forming dual ex-truded ploclder blanks. Obviously, the process according to the invention is ! adaptable when necessary to singly extruded plodder soap blanks , of special or changed formula.
The plodder blanks are rotated ninety degrees on tl-e longi-tudinal axis to stand on edge before inscrtion into a con-vcntional soap press.
~ nexpectedly, the rotation step and subsequent pressing Il I
opera-tion impart a laminar or parallel crack pattern to the ' soap bar or cake thereby eliminating stress surface cracks and wet surface cracking in soap bars.
The soap bars are pressed in the conventional dual ~I soap presses under conventional condi-tions of temperature and pressure.
